wall-bolts. And the heat pump must be installed with shockproof bushes to prevent
vibration and/or imbalance.
6.
Even though the controller is waterproof, care should be taken to avoid direct sunlight
and high temperature. In addition, the heat pump should be placed to ensure quality
viewing of the controller.
7.
The plumbing pipes must be installed with proper support to prevent possible damage
due to vibration.
Running water pressure should be kept 0. 2 Mpa to 0. 6Mpa. Otherwise, booster pump
or pressure reducing valve should be installed.
8.
The acceptable operating voltage range should be within ±10% of the rated voltage.
When heat pump units are installed in parallel, ensure that the voltage differences,
between these units, are within ±2%.
9.
The heat pump unit must be grounded /earthed for safety purposes.
10. If possible, the unit can be installed with auxiliary facility of rain, snow and sunlight proof.
Drainage and Condensation
Condensation will occur from the evaporator when the unit is running and drain at a steady
rate, depending upon ambient air temperature and humidity. The more humid the ambient
conditions, the more condensation will occur. The bottom of the unit acts as a tray to catch
rainwater and condensation. Keep the drain holes, located on the bottom pan of the unit
base, clear from debris at all times.
For the units which installed at the rack on the outer wall, proper drain hose should be
connected to the heat pump for condensation drainage.
